PURPOSE We report on the evolution in one institution from transarterial embolization for the treatment of dural arteriovenous fistulas of the lateral and sigmoid sinuses to the safer and more durable technique of transvenous endovascular therapy for the majority of these lesions. METHODS Arterial, venous, and combined embolizations were performed for 24 fistulas of the lateral and sigmoid si...

BACKGROUND AND PURPOSE Preoperative embolization for intracranial meningiomas offers potential advantages for safer and more effective surgery. However, this treatment strategy has not been examined in a large comparative series. The purpose of this study was to review our experience using preoperative embolization to understand the efficacy, technical considerations and complications of this t...

BACKGROUND AND PURPOSE Preoperative embolization of primary and metastatic spinal tumors is often performed to decrease intraoperative blood loss and facilitate surgical resection. The purpose of this study was to evaluate the safety of spinal tumor embolization and the variables that may influence intraoperative blood loss. MATERIALS AND METHODS A retrospective analysis of 100 spinal tumor e...

BACKGROUND The role of portal vein embolization to increase future liver remnant (FLR) is well-established in the treatment of colorectal liver metastases. However, the role of hepatic vein embolization is unclear. CASE REPORT A patient with colorectal liver metastases received neoadjuvant chemotherapy prior to attempted resection. At the time of resection his tumor appeared to invade the lef...

OBJECTIVES To evaluate the use of a new tumor embolization agent, Onyx (Covidien, Dublin, Ireland), for the use of intraoperative embolization of a sinonasal unclassified spindle cell sarcoma. METHODS A 45-year-old female patient presented to the rhinology clinic with a nasal mass. A biopsy revealed a highly vascular mass consistent with a sinonasal unclassified spindle cell sarcoma. Secondar...

PURPOSE To evaluate the feasibility and effectiveness of transcatheter embolization by forcible intraarterial injection of a mixture of ethylene vinyl alcohol copolymer (EVAL) and ethanol under microballoon occlusion compared with conventional transcatheter arterial embolization methods in nontumoral swine liver. MATERIALS AND METHODS Nine swine were divided into three groups: embolization wi...

background uterine artery embolization (uae) is a minimally invasive procedure performed under fluoroscopy for the treatment of uterine fibroids and accompanied by radiation exposure. objectives to compare ovarian radiation doses during uterine artery embolization (uae) in patients using conventional digital subtraction angiography (dsa) with those using digital flat-panel technology. patients ...

hemangiomas are the most common benign liver masses with a frequency of 0.4-7.3% at autopsy. they are usually discovered incidentally and a few require surgery. spontaneous or traumatic ruptures are among indications of surgery for hemangiomas. we report a case of giant hepatic hemangioma presenting as hemoperitoneum following use of the slimming belt that underwent an emergent laparotomy. abdo...

PURPOSE We report a case of hyperthyroidism in a young woman caused by Graves' disease that was successfully treated with thyroid arterial embolization. CLINICAL DETAILS A 35 year-old woman with a history of thyrotoxic crises was admitted after the last thyroid crisis. Thyroid arterial embolization was used to treat the hyperthyroidism after it had been controlled. Immediately after embolizat...
